Guy i work with bought a house where there had been solar collectors
on the roof. There is a pump down under the house and a copper tank. I
don't know what was supposed to happen here and I'm only interested in
the pump. I want to build a wood burning stove. The type with water
surrounding the firebox and the heated water is pumped into the house.
So i need a water pump for this heated water and am wondering how hot
the water on your typical solar collector is and if this pump is what
i might be looking for. I couldn't get under there to look at the pump
today and thought i'd ask here about pumps for my wood stove project.
If i remember right the stoves are designed to circulate water at
about 170 degrees with the firebox controlled with dampers
thermostatically controlled. I helped a guy with fabricating one of
these a while back and have acess to all the metal i want.

Rosco,
Typically between 120-140°F (49-60°C) for domestic hot water usually
set by a differential controller, follow the pump wirers back and you
should find the differential controller and it may have temperature
settings or markings.

Mine had a Grundfos stainless steel pump to circulate the collector.
About 75W.
